Flow limiter SP/SMB3
Flow limiter SP/SMB6
for circulating-oil lubrication systems
Flow limiters are used in large circulating-oil
lubrication systems. The task of a flow limiter
is to divide up the volumetric flow of the
main line into parallel individual volumetric
flow quantities and to “limit” these according
to requirements, or to keep them constant.
The volumetric flow generated is independent of the system pressure and virtually
independent of viscosity.
When exchangeable plug-in nozzles are
used, it is possible to adjust the volumetric
flow of the flow limiter as follows:
SP/SMB3 in steps from 6.0 to 38.0 l/min
SP/SMB6 in steps from 25.0 to 132 l/min
This enables a subsequent adjustment of the
volumetric flow.

Advantages
• reliable
perpetual dispensation of individual
volume flows
- self-adjusting metering, thus identical
volume flows despite different back
pressures.
- wide viscosity range, virtually independent of temperature and viscosity, thus
the system conditions are stable

• easy startup
Pre-adjusted volume flows enabling short
start up periods.
• effective monitoring of the volume flow
signal transmitter or piston detector react
to deviations of the volume flow from approx. 15%.
• wide range of operation, up to 200 bar

• easy system design
The demanded volume flow and flow
limiter nozzle respectively, are determined
during projection.

• optional ATEX version or integrated gear
indicator for volume flow

The volumetric flow can either be monitored
by a sensor or a piston detector (also retrofittable). A fault signal is emitted when the
volumetric flow drops to approx. 85 % of the
rated flow.
